I am wondering where the benefit of this is.  We take natural gas, burn 
it to produce energy (and CO2 and H2O).  Use more energy than that to 
convert the H2O into H2 and O2, and then the CO2 + H2 back into CH4 
again.  This seems like a machine for turning energy into waste heat and 
goodness knows we have enough of those already.  Perpetual motion 
machines don't work even if you use chemicals.  What am I missing?

Thank You Kindly,

Corwyn
